[0026] The utility model provides a portable ATP fluorescence detector.
[0027] A portable ATP fluorescence detector comprises a main body 15, one end of which is provided with an openable protective cover 1, the main body 15 is provided with a detection cavity 8 with an opening at one end, the opening of the detection cavity 8 cooperates with the protective cover 1, the protective cover 1 can cover the opening of the detection cavity 8, and the side wall of the detection cavity 8 is provided with a light detection element.
[0028] In the technical solution proposed in the present application, the utility model directly sets the detection cavity 8 on the main body 15. When performing detection, the sample to be tested is obtained through the swab sampler 4, the protective cover 1 is opened, the swab sampler 4 is placed in the detection cavity 8, ATP detection reagent is added to the swab sampler 4 and fully mixed with the sample to be tested, and the luminescence value is detected by the light detection element in the detection cavity 8. During the detection process, the protective cover 1 is closed, and the protective cover 1 covers the opening of the detection cavity 8, which can reduce the interference of external light on the detection; when detection is not needed, as long as the protective cover 1 is in a closed state, the detection cavity 8 can be shielded from light, which is very convenient.
[0029] The portable ATP fluorescence detector also includes a swab sampler 4, a sampling part of the swab sampler 4 is plugged into and matched with the detection cavity 8, and a hand-pinching part of the swab sampler 4 can be covered by a protective cover 1.
[0030] It is not necessary to put the entire hand-pinching part of the swab sampler 4 into the detection cavity 8. It is sufficient to put the sampling part into the detection cavity 8. This reduces the volume of the detection cavity 8 to a certain extent, thereby reducing the volume of the main body 15. Moreover, the hand-pinching part is located in the protective cover 1 and will not affect the anti-interference and light-shielding protection functions of the protective cover 1.
[0031] The portable ATP fluorescence detector also includes a limiting sleeve 5, which is internally sleeved in the detection cavity 8, the inner side of the limiting sleeve 5 is limitedly matched with the swab sampler 4, and the protective cover 1 is in contact with the hand-holding part of the swab sampler 4.
[0032] In a specific embodiment, the inner side surface of the protective cover 1 is in contact with the end of the hand-pinching part away from the sampling part, the inner side surface of the limiting sleeve 5 is in contact with the outer side surface of the swab sampler 4, and a reducing portion 11 is provided in the middle of the limiting sleeve 5. The reducing portion 11 becomes smaller and smaller from the end close to the protective cover 1 to the end away from the protective cover 1. The outer side surface of the swab sampler 4 is provided with a first annular protrusion 13, and the first annular protrusion 13 is matched with the large diameter end of the reducing portion 11. This structure prevents the swab sampler 4 from axial movement and radial shaking relative to the limiting sleeve 5.
[0033] The portable ATP fluorescence detector also includes a limit block 7, which is fixed inside the main body 15. The limit block 7 is arranged on the side of the detection cavity 8 away from the protective cover 1. The limit block 7 is provided with a limit hole 12. One end of the limit sleeve 5 is limitedly matched with the limit hole 12, and the other end of the limit sleeve 5 is limitedly matched with the opening of the detection cavity 8.
[0034] In a specific embodiment, the end of the limiting sleeve 5 away from the protective cover 1 is inserted into the limiting hole 12, and the optical detection component is arranged on the side wall of the limiting hole 12. The outer side surface of the limiting sleeve 5 away from the protective cover 1 is provided with a second annular protrusion 14, and the second annular protrusion 14 cooperates with the end surface of the limiting block 7 provided with the limiting hole 12. The outer side surface of the limiting sleeve 5 close to the protective cover 1 is provided with a third annular protrusion 10, and the third annular protrusion 10 cooperates with the end surface of the main body 15 provided with the opening of the detection cavity 8, so that the limiting sleeve 5 and the detection cavity 8 are axially limited, and the outer side surface of one end of the limiting sleeve 5 is tightly fitted with the side surface of the limiting hole 12, and the outer side surface of the other end of the limiting sleeve 5 is tightly fitted with the side surface of the opening of the detection cavity 8, thereby preventing the limiting sleeve 5 from axial movement and radial shaking relative to the detection cavity 8.

The opposite sides of the limit block 7 are respectively plugged in and fitted with the front shell 2 and the rear shell 3, which is only one embodiment of the installation of the limit block 7. In other embodiments, the limit block 7 can also be fixedly connected to the front shell 2 or the rear shell 3. As for these two embodiments, they will not be described here.
[0037] The main body 15 is divided into a front shell 2 and a rear shell 3. As long as the structures of the front shell 2 and the rear shell 3 are well designed, the detection cavity 8 can be directly formed by quickly connecting the two together, which is fast and efficient. The front shell 2 and the rear shell 3 can be connected to realize the positioning of the limit block 7, which is fast and efficient.
